وَإِمَّا تُعۡرِضَنَّ عَنۡهُمُ ٱبۡتِغَآءَ رَحۡمَةٖ مِّن رَّبِّكَ تَرۡجُوهَا فَقُل لَّهُمۡ قَوۡلٗا مَّيۡسُورٗا ٢٨
And if you [must] turn away from them [i.e., the needy] awaiting mercy from your Lord which you expect,1 then speak to them a gentle word.
Translation: Saheeh International (English)
1 i.e., if you have not the means to give them at present.
Each word's meaning and sound
But if you refrain from giving these people, due to not having anything to give them, while waiting for Allah to bless you with provision, then say to them gentle and polite words such as praying for them to have abundant provision or promising to give them if Allah grants you wealth.
